LXK260×3000 CNC screw milling machine
I. Introduction to machine tools
LXK260 type (external type) CNC screw milling machine is our company's own research and development of a series of screw processing machine leading varieties, the product is
designed for the processing of equal lead, variable lead, gradual lead, equal groove depth, variable groove depth and other special-purpose screw machine.
LXK260 CNC screw milling machine has the following characteristics:
1, the whole bed design, three guide rail layout, guide rail surface high-frequency quenching, good rigidity, high precision.
2, X axis and Z axis reciprocating motion using ball screw to achieve high repeatable positioning accuracy.
3, the spindle bearing is lubricated by oil, low temperature rise, high durability, and no daily lubrication maintenance.
4, C axis drive for worm gear and worm structure, smooth transmission, accurate indexing.
5, the saddle is dovetail guide rail, high position accuracy, good fast speed.
6, the milling head adopts high power frequency conversion motor, which can make the milling cutter realize stepless variable speed and wide speed range. The milling head can be manually adjusted according to the requirements of the workpiece. The milling head can go up and down.
7, the machine tail seat is mechanical, flexible and reliable.
8, the machine is equipped with chip discharging machine, the iron filings generated in the milling process directly into the chip discharging machine, to ensure the clean working environment.
9. The electrical components in the machine tool electrical control cabinet are delixi brand.
10, the machine is equipped with a wide range of control system.
